摘　　要：以国内某钢厂650mm热连轧粗轧机组为研究背景,详细介绍了带记忆存储功能前馈自动宽度控制(MFF-AWC)的控制算法及数学模型,用前机架立辊的出口带钢计算硬度经过记忆存储处理作为前馈控制的检测硬度,设计出了MFF-AWC控制模型,针对带钢宽度波动及时调节下游立辊机架的开口度,实现提前预控的目的,试验表明,MFF-AWC控制模型投入使用之后,带钢宽度精度得到明显提高。Under the background of a hot rolling strip,the control algorithm and mathematical model of the memorial feed-forward Automatic Width Control（MFF-AWC）was analyzed.The calculated strip hardness from the exit preceded stand processed by memory function was taken as the inspected hardness in feed-forward control.Based on this,the MFF-AWC model was designed,which was aiming at the timely control of the opening degree of downriver edger mill with the width fluctuation.In this way it can attain the goal of precontrol.As a result,the width precision of rolling strip was improved obviously after the MFF-AWC model was into service.
